The types of IBS

IBS-C — constipation predominant

Stools are hard or infrequent, straining is common, and a sense of incomplete evacuation lingers — together with abdominal pain. In this type, fibre, water, movement and a fixed morning routine make the biggest difference.

IBS-D — diarrhoea predominant

Stools are loose and frequent, often with sudden urgency. Here the focus shifts to meal size, meal timing and stress management, and fibre is increased slowly and deliberately.

IBS-M — mixed

Constipation and diarrhoea alternate. This feels like the most confusing type, but regularity — fixed meal times and sleep — still turns out to be the single biggest stabilising factor.

How to identify your type

For two to four weeks, note each day what the stool was like and at what time it came. Whichever pattern shows up on most days is your dominant one. That single piece of information shapes your diet guidance, the pace of practice and your meal timing.

This page is general health education, not a diagnosis. Persistent, severe or new symptoms — and warning signs such as blood in the stool, unexplained weight loss, fever, repeated vomiting or anaemia — need a qualified healthcare professional. Our guidance works alongside your doctor's care, never in place of it.
